[VAL] refrigirator fire almost

["Stan Truitt" <stan.truitt@xxxxxxxxxxxxxxxx>]

hey everyone
took the '66 safari out this week. the PO had told me that the frig (dometic)
did not work on gas so for the last couple of months i have only used it on
110v. the day prior to our trip, i followed the instructions for lighting it
on gas and it fired up perfectly. it shut down when the proper temp was
achieved and i though things were fine. i tested it on gas for half a day with
great results and traveled to our first campground with it running just fine.
when we arrived at the first campground we had 110v at the campground so i ran
it on their nickel after switching the frig to 110v. our next campground had
no electrics so i fired it up on propane. i lit the burner and saw it burning
with a nice blue flame, shut the compartment door and within less than a
minute, smelled burning plastic. i jumped up and opened up the cabinet towel
compartment which gains access to the plastic frig flue that runs up to the
trailer top for exhaust. it was melting, smoking and charred all in less than
a minute. i opened the lower inside compartment door of the frig and saw the
same blue flame. it was only about 1" tall but did burn with alot of force.i
got things shut down and needless to say did not fire it up again. i now am
trying to figure out what happened and if anyone else has experienced this.
the plastic flue is clear of any debris such as mouse or bird nests etc.
perfectly clear and has air flow.  access to the upper portion of the frig is
nearly impossible without removing it which i will do if necessary but i need
some ideas as to the problem. did something move, slip or become mis-aligned?
what happened? help!!  thanks
